About electronvolts and watt-hours
The Conversion Formula
To convert electronvolts to watt-hours, multiply the value by the conversion factor: 1 eV = 4.4505e-23 Wh. For a worked example, suppose you need to convert 25 eV to watt-hours: 25 × 4.4505e-23 = 1.1126e-21 Wh. To convert in the opposite direction, divide by 4.4505e-23, or equivalently multiply by 2.2469e+22.
About electronvolts
The electronvolt (eV) is the tiny unit of energy used in particle physics. It is the energy gained by an electron accelerating through 1 volt. It is essential for describing photon energy, chemical bonds, and nuclear reactions. electronvolts are commonly used in Particle physics, Semiconductors, Nuclear energy, and Chemistry bonds, Microscopy.
A photon of visible light has an energy of about 2-3 eV.
About watt-hours
The watt-hour (Wh) is a smaller version of the kilowatt-hour. It is the standard for rating the capacity of batteries in laptops, smartphones, and power banks. Airlines often limit spare batteries to 100Wh for safety. watt-hours are commonly used in Laptop batteries, Power banks, Smartphone specs, and Drone batteries, Portable speakers.
A typical phone battery holds 10-15 Wh.
When Would You Convert electronvolts to watt-hours?
Converting between electronvolts and watt-hours is one of the most common energy conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 eV = 4.4505e-23 Wh) memorized or bookmarked can save time in professional and everyday contexts alike.
